Abstract

The invention provides an earthquake prediction method and device, and electronic equipment. The method comprises the steps of obtaining an earthquake catalog and a seismic mechanism solution of a target earthquake event; determining the tidal stress of the epicenter of the earthquake event according to the earthquake catalog; based on the tidal stress and the seismic mechanism solution, determining loading and unloading effects of the tidal stress on a target seismic event; and according to the loading and unloading effects of the tidal stress on the target earthquake event, determining a prediction result of subsequent earthquakes in the epicenter. According to the method, the earthquake is quickly predicted in real time through the earthquake catalog and the seismic source mechanism solution, so that the timeliness of earthquake prediction is improved.

Description

technical field [0001] The invention relates to the technical field of earthquake prediction, in particular to an earthquake prediction method, device and electronic equipment. Background technique [0002] The petrological test proves that the fracture process of the rock is stable before loading to the expansion point, and there is no self-organization criticality; after loading to the expansion point and before the strength peak, the fracture is unstable and will develop spontaneously. At this time, the system has Self-organization; only when it is loaded to the peak intensity point, the system has the criticality of self-organization, and instability occurs under the slight disturbance. It follows that the system is not always in a self-organizing critical state. [0003] The traditional earthquake prediction is generally based on the loading and unloading response ratio method. In actual operation, the seismic energy released in a certain time window and space window i...
